The Covid-19 pandemic that has hit since 2019 has claimed many lives. With a high transmission rate and various mutations, the Covid-19 virus has spread to many countries in the world.
Not only Covid-19, there are several diseases that are also deadly and cause many cases of death. Of the 56.9 million deaths worldwide in 2016, more than half or 54% were caused by the top 10 causes of death in the world.

The World Health Organization (WHO) says ischemic heart disease and stroke are the world's biggest killers, with a combined 15.2 million deaths in 2016. These deadliest diseases are generally caused by poor diet and several other causes.

1. Coronary Artery Disease

In the first place there is coronary artery disease. This disease is also known as ischemic heart disease. This disease can appear without symptoms, chest pain to heart failure.

The cause of this disease is due to the narrowing of blood vessels in the heart so that it follows the risk of having a heart attack. Coronary artery disease or ischemic heart disease is still the number one killer disease in the world.

2. Strokes

The sequence of the next deadly disease is a stroke. Stroke is a disease that occurs when an artery in the brain becomes blocked. Symptoms experienced by stroke sufferers generally feel numbness in all or part of the body, difficulty walking, and confusion.

If this happens, the brain will experience a lack of oxygen. Furthermore, brain cells will die within a few minutes. Meanwhile, if this disease is treated quickly and precisely, it is likely that the sufferer will recover. However, if treatment is delayed, this disease can cause long-term disability for the sufferer.

3. Alzheimer's and Dementia

Alzheimer's and dementia are rarely associated with risk of death. However, both of these diseases can cause memory loss which gradually causes mental and memory damage to the sufferer.

This disease is caused by mild memory problems such as not being able to remember something. Until finally brain function will decrease until it results in death.

4. Respiratory Cancer

Respiratory cancer is the next deadly disease according to WHO. Respiratory cancer which includes cancer of the bronchi, trachea, to the lungs and larynx is reported to be a disease that causes around four million deaths each year in 2015.

There are several factors that cause this disease to occur. Among them cigarette smoke, toxic particles to poor air quality.

5. Chronic Obstructive Pulmonary Disease (COPD)
